Dear list,
I'm using solve(A,b) to solve (!) a linear system, where A is a large (100 x 100) symmetric, dense, complex matrix. The precise structure of A is block-Toeplitz, which means that the best algorithm for inversion would probably be based on fft. Anyway, I'm looking for an iterative solver similar to Matlab's GMRES (Generalized Minimal Residual) routine as I could use an initial guess (I need to slightly change the linear system many times) and specify the maximum number of iterations or a level of accuracy to maintain an acceptable computation time. Do you know of an R interface to such iterative schemes?
